Oblivion probably has my favourite Thieves Guild and Fighters Guild in the series. Dark Brotherhood was great too. Probably had more fun with Oblivion's Dark Brotherhood quest line than I did with any other faction in the series.

My main issues with the game were the dungeons and enemy level scaling. Wasn't a fan of how Bandits eventually all had glass armour and certain enemies disappeared from the game entirely. I like Morrowind's method the best although I do like how Skyrim took the Oblivion route and improved it.

I replayed the game earlier this year and really liked something I didn't really appreciate on my first playthrough. The game is so damn colourful. In a world filled with brown and grey games, it really stood out. The game still looks great if you ignore character models.

I freaking love this game and still hold it as the best in the series. The guilds were top notch, there were sidequests everywhere, secrets to find, really the series at its peak. Aside from a few gameplay improvements in Skyrim, it wasn't really that great in my eyes. Dragons got old quick, the guilds were disappointing at best, and there were few memorable quests. That only elevates Oblivion in my eyes.

Loved this game too. One of the few I have played over 100 hours. I've had Skyrim since it came out, but have not played it more than 2 hours because I know I won't be able to do anything else if I start it. Waiting until my backlog isn't as huge.
